Mercy

Exiled angel Mercy "wakes" as unhappy teen Lela, who cares for her dying mother but never herself, and as Mercy begins to remember Ryan, the boy she fell in love with in another life, and Luc, the angel haunting her dreams, she must decide whether to risk Lela's life to gain her heart's desire.

Mercy, a fallen angel, is doomed to an eternity of living someone else's life, but when she meets Ryan, an eighteen-year-old who refuses to believe his missing twin sister is dead, she realizes she can help him, even if it means exposing her true self and taking a chance that her efforts will be rejected.
